Definitions

  • the invention relates to a hand-held launching device with a plurality of cartridges according to the preamble of patent claim 1.
  • Each firing pin was on a plate. When the firing pin unit was inserted, each release latch snapped in front of the corresponding plate. All firing pin springs were tensioned by further insertion. When the firing pin units were inserted, the trigger was tensioned automatically. Each release pawl was secured by a slide that could be moved in the longitudinal axis of the cartridge on the outer casing of the loading unit and which reached under the release pawl. The release pawl could only be triggered when this slide was moved against a spring force.
  • the object of the invention is to provide an easy-to-use and safely functioning launch device, which is particularly easy to hold and, if it is used as a hand launch device, puts an attacker out of action without killing him or permanently injuring him.
  • the hand-held launching device with a corresponding active ingredient is preferably used by the police, prison staff or private security companies. If another active ingredient is used, there are other possible uses, such as B. fire fighting possible.
  • the object is achieved in that, in contrast to US-A 1, 741, 902, in the case of a launcher with a cartridge receiving unit in which a plurality of cartridges, each with a propellant charge, are interchangeably arranged in a receiving space, and in which the rear part of the device is one final and the cartridge replacement enabling the cartridge replacement, not a solid projectile, but a fluid and / or powdery active ingredient is used as a product to be ejected. Furthermore, in contrast to US-A 1, 741, 902, only a sequential triggering can take place in a compact, space-saving configuration. In contrast to US Pat. No. 1, 741, 902, the person operating the device does not have to remember which cartridge he has just fired, since US Pat. No.
  • 1, 741, 902 permits simultaneous "firing" of several or all cartridges. In the heat of the moment, it can happen that all cartridges are fired at once and that there is no means for re-firing if the first firing did not hit. Since the active substance stored in the cartridges can always impair the user, if the firing device is a self-defense device, a constructive design is selected which, at least when the cartridge is fired, creates a seal so that no active substance remains outside the cartridges in the firing device.
  • the seal can either be arranged on the cartridge or in the space accommodating the cartridge.
  • the seal can now preferably be carried out with a sealant which seals the head region of each cartridge against the wall of the receiving space in a fluid-tight or "powder-tight" manner. It can also be sealed off from the antechamber. Sealing against the nozzle antechamber has the advantage that almost no active substance can remain, since all the active substance is expelled by the propellant gases.
  • the cartridge is sealed only in the head region, it is mechanically simpler to carry out, minimal active substance residues then only remain in the region between the seal and the active substance outlet or nozzle outlet. These minimal active substance residues should have no effect on the operator of the launcher, since when the cartridge is changed the cartridges are only touched at their rear end facing away from the active substance outlet. This area is clean because the seal should be placed as close as possible to the active ingredient outlet from the cartridge.
  • the sealing of the cartridges is by no means limited to the firing devices described below.
  • a sealing ring arranged in the head region or in the nozzle antechamber can be used as the sealing means, which can then be held in a groove in the cartridge wall or in a groove in the receiving space.
  • glued-on elastic rings or coatings can also be used, which would then preferably be attached to the cartridge.
  • a sealing means as a separate mechanical construction part can also be completely dispensed with, in that, by means of a suitable material and a corresponding geometry, the cartridge sleeve assumes the sealing task due to its expansion during "firing" even by being pressed in. When it is fired, the outer contour of the cartridge expands.
  • the receiving space and the cartridge can then be designed with tolerances in such a way that, especially when firing, a seal is preferably made in the area of the cartridge head. Compared to an existing sealant, however, small mechanical tolerances must be observed. Structural elements can also be used, which result in a seal by itself. This sealing can also be carried out by a corresponding selection of materials, in particular in the cartridge case.
  • a separate sealant (sealing ring or similar) is used, a greater tolerance can be selected between the outer wall of the cartridge and the inner wall of the recess, which results in easier replacement of the cartridges, since jamming is greatly reduced.
  • the shape of the nozzle antechamber can also contribute to reducing the back pressure and the resulting material backflow when firing, by making it aerodynamically (e.g. funnel-shaped) towards the part of the nozzle that is essential for jet shaping.
  • a separate sealing element can then be dispensed with.
  • the nozzle antechamber is then part or extension of the cartridge receiving space.
  • a bar-like launch device which can also be designed as a hand launch device, for example, is understood to mean a device that does not have a knob.
  • Typical handguns pristols, revolvers, ...) have a pommel.
  • the launcher described here can be designed in the broadest sense as a "beating", stick or the like. It is also not a shape based on a rifle or a "bazooka”.
  • the design of the launcher as a hand launcher now allows it to be shot with only can be held in one hand, but this should not be confused with the typical handling of hand or hand guns.
  • the bar-shaped hand launcher is held in the enclosing hand with the arm angled upwards in such a way that the hand is approximately at shoulder height and the back of the device opposite the active substance outlet comes to rest on the thumb side in the hand.
  • the launching device has the beam-like outer contour when it is in the operating state, ie not when the cover part is folded down.
  • the cartridges will preferably be arranged coaxially to a longitudinal axis of the launcher at a radial distance that is the same up to a tolerance.
  • the cartridges do not have to be arranged at the same radial distance.
  • such a construction has the advantage that it simplifies the arrangement of the firing pin.
  • the launching device is preferably designed such that all planes of symmetry of the cartridge group intersect in a line; an odd number of cartridges would result in a star-shaped arrangement.
  • This line can then, but need not, be the central axis of the device at the same time, which results in an aesthetically pleasing design and an easy-to-use device.
  • Another position of the cutting line can of course also be selected. Only the securing element described below slightly disturbs this symmetry.
  • Cartridge arrangement can be omitted if, for example, accessories are to be attached to one side of the device.
  • the cutting line is the central axis of the device, then all the essential functional elements are either in or symmetrical along this central axis.
  • the release button and a switching device for the sequential release can then also be arranged in the central axis.
  • the cartridges can be arranged rotationally symmetrically around the central axis.
  • the release element is therefore arranged in the rear end face of the cover part in the beam-like outer contour and can be operated with the thumb. It does not have to be operated with the thumb; the thumb is a good idea. It could also be operated by turning the hand with another finger.
  • a separate charging unit for "arming" the trigger unit.
  • the loading unit only allows arming when the lid part is closed.
  • the charging unit also has a charging element which can be operated in particular from the front end of the cartridge receptacle unit, the device also only having to be held in one hand. This enables all cartridges to be armed with a single handling possible. You can also press the front of the launcher against an object or against the ground.
  • the cartridges are arranged symmetrically to the loading element.
  • the release element can be secured against being pressed in by a movement block by the securing unit.
  • the striking motion of the firing bolt striking the propellant can also be fixed in motion by the securing unit and the fixation can be arranged to be canceled with the securing unit.
  • each receiving space is closed off with an outlet nozzle that matches the cartridge, and the part of the nozzle that is relevant for the beam shaping is preceded by a space for accommodating parts of the cartridge head.
  • the outlet nozzles with the nozzle space or free space are not integrated in the cartridge, but in the cartridge receiving unit.
  • the cartridges are simply constructed with an active substance storage space, a sabot and a propellant charge acting on the sabot, the cartridge head being designed to be tearable.
  • a perfect opening of the cartridge head is then given in the free space when firing.
  • the propellant charge is preferably pyrotechnic and can be ignited by striking a firing pin.
  • the tearing open is "flower-like", ie there is a burst without parts flying off.
  • the burst parts are given space in a free space in front of the part of the nozzle that is relevant for the jet shaping, i.e. before the nozzle entry, so that the burst parts of the cartridge head do not impair the jet flow through this part of the nozzle and thus a perfect opening of the sleeve head into this space given is.
  • This free space is therefore part of the cartridge receiving space or its extension.
  • the cartridge-receiving space can also be circular-cylindrical with a diameter larger by a tolerance.
  • the cover part can be opened or swung open relative to the cartridge receiving unit.
  • the cross section of the space accommodating the cartridges in the cartridge accommodating unit can be designed to taper to the free space. A minimum cone angle between 0.30 ° and 0.45 ° is preferably selected for the taper.
  • this pressing-in can also be used to seal the cartridge head against the inner wall of the receiving space.
  • the conical design of the receiving space has proven itself in all types of launching devices which work with exchangeable active substance cartridges and is not limited to the beam-like outer contour.
  • the cartridges have been designed to be inexpensive. When fired, the cartridges expand more or less. So that the action of the active ingredient remaining in the device can now be completely prevented when the cartridges are replaced, the amount of propellant is chosen so large that the active ingredient is completely expelled.
  • the sabot and the inside of the cartridges can, for example, as described in EP-A 1 158 263, have a pressure relief means on the inner wall, which forms a passage for the propellant in the upper part of the cartridge between sabot wall and inner wall.
  • each cartridge can have a first latching element on its jacket, preferably in the lower area which receives the propellant.
  • the loading element will then preferably be designed as a spring-loaded rod with a second locking element matching the first, both then latching into one another when the loading element is pressed in and, when the cover part is opened, the cartridges are ejected or in by a renewed insertion of the loading element as a result of the still existing locking connection a handle Position can be brought.
  • an irritant liquid or an irritant gas is generally used as the active ingredient; however, powdery substances can also be used.
  • liquid active ingredients are those listed below
  • Capsaicin is an extract from the chilli pepper plant, which is usually dissolved in alcohol at a concentration between 1% and 4%. Capsaicin leads to sudden, transient inflammation of all mucous membranes with which it comes into contact (e.g. eyes, respiratory tract). Capsaicin works in both humans and animals. In contrast to the Lacrimonium listed below, it leads to the involuntary closing of the eyes.
  • a CS solution can be used as another liquid active ingredient.
  • CS is a tearful lacrimonium. As an additional effect, there is a strong itching on the skin. CS only works in humans.
  • CN solutions can also be used. CN causes nausea. However, it works slower than a CS or capsaicin solution.
  • Stink secretions can also be used as liquid active ingredients. Most smelly secretions also cause nausea.
  • CS and CN can also be used in gaseous form instead of a liquid active ingredient.
  • powdery active ingredient for self-defense e.g. capsaicin
  • capsaicin can also be used, which is crystalline in its pure form at room temperature.
  • solutions work faster than applied powdery active ingredients.
  • powdery active ingredients have the advantage that they remain in the room for a certain period of time as a cloud.
  • Mixtures of liquid and gaseous substances can also be used as the active substance. These are often foams that stick to the attacker to be defended. Capsaicin can also be used here. Mixtures of solid and liquid active ingredients often also contain capsaicin. These are, for example, gels. Dyes can also be used for the subsequent identification of a perpetrator.

  • its bottom part which is designed as a bursting disk 121, has the score lines 135 which can be seen in FIG.
  • the propellant cartridge 128a / b is designed to be diffusion-tight, preferably as an extruded metal sleeve which is completely diffusion-tight against the liquid reservoir through the front 136a / b.
  • the front side 136a / b which in the variant 136b is a flat metal disc, is then torn apart by the resulting hot-tensioned gases when the propellant powder 139 is ignited such that the front surface parts separated by the score lines 137 burst open into the free space 131 in a flower-like manner.

Care must then be taken, however, that during "firing", a largely elastic expansion of the cartridge head results in a fluid-tight pressing against the wall of the cartridge receiving space 155. In order for this expansion to take place sufficiently, the wall thickness of the cartridge sleeve 130 in the area of the cartridge head could be reduced with a corresponding tolerance selection.

Abstract

L'invention concerne un dispositif de tir (1) tenu à une main, comprenant, d'une part, une unité de logement de cartouches (11) dans laquelle plusieurs cartouches (3a-3d) présentant chacune un agent propulsif (132) sont placées de manière interchangeable dans un logement (9) respectif, et, d'autre part, une partie couvercle (7) obturant la partie arrière de l'appareil et permettant le remplacement des cartouches. Dans chaque cartouche (3a-3d) est stockée une substance active (14) fluide et/ou pulvérulente pouvant être éjectée au moyen de l'agent propulsif (123), une fois ce dernier activé. La partie couvercle (7) comporte des unités de déclenchement destinées aux cartouches (3a-3d) et pouvant être activées de manière séquentielle au moyen d'un élément de déclenchement (21). L'unité de logement de cartouches (11) et la zone de tête de chaque cartouche sont adaptées l'une à l'autre de sorte que, au moins après le tir d'une cartouche, une étanchéité soit créée vis-à-vis du logement de cartouche (9) afin d'empêcher qu'une quantité importante de substance active (14) ne reste dans l'appareil (1), à l'extérieur de la cartouche (3a-3d), et d'éviter ainsi de gêner l'utilisateur lors du remplacement des cartouches.
